Description of key information

Considering the chemical structure of the substance and taking Appendix 6 of UN regulation for the use of screening procedures to assess explosive properties and the ECHA Endpoint specific guidance (R.7a) into consideration, [µ-[carbonato(2-)-O:O']]dihydroxydioxodizirconium (ZBC) is considered not to contain any chemical groups indicating explosive properties.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

Based on Column 2 of the REACH regulation on standard information requirements (Annex VII), the study does not need to be conducted if there are no chemical groups associated with explosive properties present in the molecule. Considering the chemical structure of the substance and taking Appendix 6 of UN regulation for the use of screening procedures to assess explosive properties and the ECHA Endpoint specific guidance (R.7a) into consideration, [µ-[carbonato(2-)-O:O']]dihydroxydioxodizirconium (ZBC) is considered not to contain any chemical groups indicating explosive properties. The thermal stability of [µ-[carbonato(2-)-O:O']]dihydroxydioxodizirconium (ZBC) is furthermore confirmed by the results of the DTA analysis (determination of the melting point) which shows no significant exothermic reaction over the temperature range studied (room temperature up to 1000°C).
